Abstract
This paper develop simulation models to analyses the effect of water supply parameters and structural parameters on radiant surface average temperature, radiant surface temperature range and temperature loss of three types capillary ceiling radiant cooling panel (CCRCP). In order to improve cooling capability of CCRCP, a lower water supply temperature should be applied. The best water supply velocity is around 0.11m/s. The suitable panel thermal conductivity is around 1 W/(m•K). Radiant surface should have higher emissivity. The G-type CCRCP have the best temperature uniformity, and the uniformity decreases in the order of G-type, U-type, S-type. Water supply temperature of U-type CCRCP can be lower when water supply velocity is slow, and water supply temperature of G-type CCRCP and S-type CCRCP can be lower when panel thermal conductivity is low.
